Dress to impress. Do not dress in the trend of the day. Dress like you want the job. Guys wear nice slacks or chino type pants. A nice unwrinkled shirt, and nice shoes. Ladies, wear nice slacks, skirt or dress, and shoes. And a nice blouse. Be well groomed. Style your hair attractively. Girls, don't over do the makeup or perfume. Make sure your nails look nice. Have your teeth freshly brushed and your breath minty fresh.
Do not go in with a hurd of your friends and ask for an application. Go alone, and act mature. Speak up, smile and give a firm handshake. You only get one chance to make a first impression. If you have piercings beyond your ears, think about if you really want to wear them. While the attitude of the day is "People need to accept me for who I am, not by what I look like" is nice thought but unfortunitely people do judge. Keep the personal statements for your private time, or until you land the job and have figured out the way things work, and what is expected. Be upbeat and positive. Realize that YOU need the job, but the employer has choices nowdays and he/she can pick and choose. Realize that any job is a good job if it is honest, legal and you do your best. Understand that you are not going to be made CEO at 17 or 18 with no experience, that generally take a college education and experience. There are jobs out there..fast food is always hiring...look at retail establishement as well. Even part time is better than no time.
Go prepared with a resume' and references. DO NOT USE your buddy, or girlfriend as a reference. Use teachers, neighbors, people you have babysat or mowed lawn for, or you have watched their house while they were away...etc.
